/* 共享外壳 v2（四套皮肤只有这一条）
 *
 * 2026-10-27 老板在真机上逐条批注后重做。上一版是「报头右侧一条栏 + 右边一列
 * 竖向书签」，结果是：正文被那列书签挤掉 58px，手机上只显示「今…」；
 * 设置页还留着一大片空白。这一版只做四件事：
 *
 *   1) 外壳改成一根竖列：报头 → 功能栏 → 标签页 → 正文。
 *      没有左右栏，正文吃满宽度（老板要的「全屏」）。
 *   2) 功能栏只剩一条，居中：此刻 / 换肤 / 昼夜 / 全屏 / 我的。
 *      44×44 一格，指针落上去整格长开（Uiverse Admin12121）。
 *   3) 标签页照搬 Uiverse Spacious74 的 radio-inputs：一整条槽里
 *      选中页与纸面同色，两侧用 10px 圆挖出凹角，看着是从纸里长出来的。
 *   4) 「全屏」= 报头和标签页整条让开，只留功能栏与正文。
 *
 * 颜色只读 forms-fx.css 给的 --sq-* 令牌，四套皮肤自动跟着变。
 * 纸墨信笺（apps/shared/chrome.css）用的是同一套几何，改这里记得对那边。
